The difference in that analogy is that life isn't spare parts.
Mammals all look quite similar in early fetus development. The forming cells are dictated what to turn into, based on the species. A small amount of changes in that cycle can produce new genes quite quickly.

Nothing earth shattering from what I read in your post. Genetic drift does seem to be a pervailing part in human evolution over the past little while, and I don't see that changing. Since the gene pool is the world over, there's a big range of genes. Even the next mass extinction may not kill off hu...

To clarify: Evolution- Changes in gene frequencies in a population over time. Adaptation- The ability for an individual to adjust to its surroundings such as enviornment. Plasticity- The range that an individual characteristic can develop in an organism (e.g. height can be different for an individua...
